2,3:4,5-bis-O-(1-methyl ethylidene)-β-D-fructopyranose is also called diacetonefructose, which is an important intermediate for drug synthesis, and contains chiral carbon atoms. In this study, one-dimensional (i.e., 1H NMR, 13C NMR and DEPT135) and two-dimensional (i.e., 1H-13C HMBC, 1H-13C HSQC, 1H-1H COSY and NOESY) NMR methods were used to elucidate the structure of this compound. The 1H and 13C NMR chemical shifts of the compound were assigned. Theoretical calculation was used to confirm the correctness of the stereochemistry configuration deduced from the NMR data.
